To all wlw/m t may conce/m.'

Be it known that I, FRED C. NELSON, a citizen of the United States, residing at Oakland,` in the county of Alameda and State of California, haveinvented new and useful improvements lin Needle-Threaders, of which the "following is a specification, reference beinghad therein to the accompanying drawings. 1

My' `nvention relates to needle 'threaders Vembodying a frame carrying ahook adapted to be projected through the eye of a Vneedle for picking up the thread, which may then be drawn through the needles eye by` Figure 1 is asidev elevation Vof my iinproved needle threader.

Referring to the drawings in detail, throughout which like reference characters designate like parts- The numerals 1 and 2 designate a pair of spaced apart flat side pieces, unitarily connected together at their lower edges as at 43, of a frame designated by the numeral 4.

In Fig. 9 is illustrated a blank stamping of theV frame 4 before the side members 1 l Syp ecication of Letters Eateiit.

and 2 have been struck upwardly, as best depicted in Figs. 1 and 10.

in striking the stamping, illustrated in 9, from sheet metal stock, I provide a pair of openings 5 and 5a, of equal diameters, spaced equal distances from one end of the stamping and equal distances from the respective side edges thereof. At the opposite end of the stamping is cut a slot 6 havingp'arallel sides 7 and S, anda semi circular end 9. The arrangement of said openings and slot is such that when the frame has been struck into shape as in the inished article asbest depicted in Fig. 1, the openings will be oppositely disposed and in axial alineinent with each other, and the slot at the other end will form an undercrop 10 in the lower edge of the members 1 and 2, in which the sides 7 and 8 extend Vparallel with the upper edges of said mein- 'beis, and said semi-circular end 9 forms a line describing a quadrant extending approximately from a point fornied by about the 280th degree of a circle to the 360th degree thereof.

The under-crop l0 is primarily adapted to form a vertical slot or opening 11 extending from the upper to the lower edges of the fraine, therebyV forming a pair of spaced apart tongues 12, 13, between which tongues tlienpper portion of a needle indicated in the drawings by the letter A,I and provided with an eye designated by B, may be made to operatively slide. D designates thread.

The free ends Vof the members l and 2 are bent 'outwardly as at'14 to permit the needle A a freer entrance into the slot 11.

V15 is a sheet metal stamping, shown in blank inFigs. 5 and G. v

`16 designates the upper shank, 17fthe lowerV shank, and 18 the crooked end, of a threading hook. VThe shank 16 is disposed, approximately 'at on angle of 45 degrees from the horizontal. upon one side of the stamping 15, in which position it is intended to be rigidly clamped by doubling the member 15 upwardly as shown in Figs. 7 and 8.

After the member 15 has been doubled as aforesaid, Ait is inserted between the menibers 1 and 2 (see Fig. 4), after which its free end is struck to one side over the top edge of the member 1, thence down along one side thereof and up along the outer side of the member 2. It is intended that the aforesaid assembly vof said parts, including Vthe shank 16, shall rigidly secure them,l together.

The shank 17 projects outwardly below the under-crop 10, in a vertical plane with the slot 11, and at an angle downwardly from a horizontal plane extending through the point of intersection of said shank with the shank 16.L

To operate my needle threader, the upper end of a needle A is inserted between the Y members '7 and 8 and the crooked end 18 v Having described my invention what lY claim vas lnew 'and desire to secure by Letters Patent, is:

I LA needle lthread'er ofthe class described, embodying a frame comprising a pair of flat side pieces .spaced a distance vapart and extending parallel lwith each other, the'` loweredges of the side pieces unitarily connected together, theV arrangement thereof being such as to form a U iii-cross section having arms vertically extended, a reinforcing ribbon having a portion disposed between said side pieces in-V termediate -their ends and another portion embracing them Yby engaging their outer sides, an under-cut on the lower side of the frame extending from onevend thereof k.to said. reinforcing ribbon, the free ends of said end of the frame being bent outwardly 'in directions away from each other, anda hook vdisposed infsaid under-cut and having one end rigidly secured to lsaid ribbon between said side pieces. Y

2.v In a device of the kind described, the

combination kwith a frame comprising two flat side pieces, sides of lsaid pieces disposed in close relation with each other, the lower edges of the side pieces rigidly connected together, thearrangement being suoli as to formfa U in cross sectionhaving arms vertically extended, of a sheet metal ribbon having one end doubled back upon itself and embracing one, end of the shank of a hook,

said end of the ribbon disposed between the arms of the U, the other portion of said ribbon embracing the frame laterally, an

Vunder-cut on thelower side of the frame between said ribbon and one end of the side pieces', the free end of said shank projecting into said under-cut and disposed in a vertical plane extending longitudinally Vthrough the frame, and a thread engaging a crook at said free end of the hook shank.

3. A needle threader embodying a frame comprising a pair of at side'pieces spaced a comparatively short, distance apart with one ofthe flat sidesv of one/next to one of the flat sidesy of the other thereof,'the lower edges of said side pieces` unitarily joined together, the arrangem'entbeing` such as to form a U incrosssection having arms vertically extended, a sheet metal ribbon having one end foldedV backwardly Vforming thereby a U having one of its arms substantially longer thanthe other, a hook shank having one en d disposed between said fold, said foldedend of the ribbon disposed between said side pieces intermediate the ends thereof, .the lower end of said last mentioned U terminating shortof the Alower edgeof the frame, the free'end of ksaid long arm folded laterallyof the frame over the Yfree end of thevshort armpand laterally over the upper edge of one of 4said side pieces and downwardly alongv the outerv side thereof to the outer side of the other side lpiece terminating adjacent the upper edge ofthe latter, theY arrangement being `such ythat said long arm may .embracev said side pieces to cause them to clampsaid Yfoldedrend together upon said hook shank to rigidly secure it t erebetween, an under-crop cut in the lower edge .ofthefraine and extending from Vone end thereof to a point adjacent said ribbon, the free end of rsaidhook shank projecting into said Vunder-crop, lsaid free end diverging downwardly at a slight angle from-the horizontal and,v disposed in a yerti cal median plane extending longitudinally through the frame, and a thread engaging crook on said free end of the hook shank, the outer or free end of said hookshank disposed at an angle with the inner orsecured end thereof.

ln witness that I claim 'the foregoing as my own, I have hereunto Ysigned Ymy name this 1th day of May. 1920.'
